* Use PowerArm only under the supervision of an adult
* Keep others away from the excercise area
* Never let go of the ball while under tension
*Always keep some tension on tubes to prevent flopping motion and possible release of the snap hooks
* Begin your excercise with minimal resistance
* Increase the resistance slowly to prevent injury
* Do not stretch tubes more than 6 feet
* As arm strength increases, change to a more resistant tube or add a second tube
* Inspect tubes regularly for wear and tear. Replace as necessary
* Secure PowerArm when not in use
